A method for charging a battery includes charging the battery with a constant charging power until a battery voltage reaches a predetermined voltage. After the battery voltage reaches the predetermined voltage, charging the battery with a first charging current at least once to a voltage threshold that exceeds the predetermined voltage. A charging time in the charging process with the first charging current for the first time is a predetermined value. Subsequent charges provided in the charging process with the first charging current is a changing value according to a battery capacity. The voltage threshold exceeding the predetermined voltage is changed according to voltage variations in the charging process with the first charging current.
